Cardiomyopathy is a cardiovascular condition that causes degeneration of the heart and thinning of heart muscle walls. These thin walls then stretch due to blood pressure inside the heart, resulting in an enlarged heart. This condition leads to sudden death around 6-8 weeks of age.

Initial signs can include severe congestive heart failure, breathing that is rapid and/or heavy, a blue tongue, excessive drooling, or collapse.
A veterinarian will review health history and conduct a thorough exam that includes clinical signs to help diagnose this condition. Laboratory testing and imaging as well as echocardiograms (ECG) may be performed. Genetic testing can determine if there is a mutation present.
